Systems and methods for puncture closure
First Claim
1. An apparatus for closing a puncture in a vessel wall comprising:
- an anchor shaft having a distal end and a tip,an anchor disposed on the distal end of the anchor shaft, a distal end of the anchor is proximally spaced apart from the tip of the anchor shaft and adapted for being in a deployed position and un-deployed position, wherein the anchor is adapted for being in the deployed position within a vessel lumen and is further adapted for being moved into contact with an inner surface of a vessel wall, andan approximately dome-shaped heating element having a lumen and a distal opening for passing the heating element over the anchor shaft, wherein the tip of the anchor shaft is seated in the heating element upon retraction of the anchor shaft, the heating element adapted for being disposed outside the vessel wall, the heating element and the deployed anchor being adapted for disposing the vessel wall there between and wherein the heating element is capable of heating when the anchor is deployed and when the anchor is un-deployed.

Abstract
Systems, apparatuses and methods are provided for use in closing punctures in vessel walls. An apparatus may have various combinations of an anchoring device, a positioning device and a heating element for closing a puncture within a vessel wall. An anchoring device may be a balloon, an expansible cage, a wire operated T-anchor, and/or a floating anchor. A positioning device may be a balloon, a sponge, and/or an expansible cage. A heating element may be flexible or rigid and preferably provides heat to target tissue through conduction and convection. A heating element may be flat-ended or dome-shaped. The heating element and anchoring device may be positioned a fixed distance apart to sandwich tissue between the heating element and the anchoring device. The heating element may operate in multiple stages. An initial stage may non-permanently adhere the heating element to the tissue and the subsequent stage may close the puncture.
